Abstract: A cross reality system enables any of multiple types of devices to efficiently and accurately access previously stored maps and render virtual content specified in relation to those maps. The cross reality system may include a cloud-based localization service that responds to requests from devices to localize with respect to a stored map. Devices of any type, with native hardware and software configured for augmented reality operations may be configured to work with the cross reality system by incorporating components that interface between the native AR framework of the device and the cloud-based localization service. These components may present position information about the device in a format recognized by the localization service. Additionally, these components may filter or otherwise process perception data provided by the native AR framework to increase the accuracy of localization.

Abstract: The techniques disclosed herein provide a synchronization engine that operates in conjunction with a service worker to dynamically store and update a working set of user data and single page application (SPA) resources from a network server to a user device. The working set can be hosted across several domains and identified by association with a user account. Accordingly, the synchronization engine retrieves the working set from the network server to enable offline execution of the single page applications. As such, subsequent requests for interacting with a single page application are then serviced by the synchronization engine using the working set retrieved from the network server. For instance, the service worker can bind user data to the application resources to enable progressive rendering through an application controller using locally available resources. In this way, the disclosed system provides a consistent user experience irrespective of network connectivity.

Abstract: A valve system controls flow into a downhole production string, and which includes a downhole valve with a port formed in a sidewall of a production string disposed in a wellbore, and a sleeve that is slidable along the production string to block or allow flow through the port. An actuator assembly exerts a sliding force onto the sleeve, and is made up of multiple actuators arranged along an outer surface of the production string. Each actuator has an electrically powered motor and a stem connected to the motor. An opposite end of each stem connects to an end of the sleeve. Energizing the motors causes linear movement of the stems and connected sleeve to open and close the valve.

Abstract: A cross reality system enables any of multiple devices to efficiently and accurately access previously stored maps and render virtual content specified in relation to those maps. Both stored maps and tracking maps used by portable devices may have wireless fingerprints associated with them. The portable devices may maintain wireless fingerprints based on wireless scans performed repetitively, based on one or more trigger conditions, as the devices move around the physical world. The wireless information obtained from these scans may be used to create or update wireless fingerprints associated with locations in a tracking map on the devices. One or more of these wireless fingerprints may be used when a previously stored map is to be selected based on its coverage of an area in which the portable device is operating. Maintaining wireless fingerprints in this way provides a reliable and low latency mechanism for performing map-related operations.

A process of the disclosed technology can include steps for displaying a user interface (UI) on a remote assistance system, wherein the UI comprises at least one chargeable button, detecting a user engagement with the at least one chargeable button, wherein the user engagement is configured to communicate one or more commands to an autonomous vehicle (AV) that is communicatively coupled to the RA system, performing a latency check to determine a latency between the AV and the RA system, and aborting the one or more actions on the AV, if a determination is made that the latency exceeds a predetermined threshold. Systems and machine-readable media are also provided.

Abstract: A bi-directional valve with valve elements having compliant features biasing them together to maintain a sealing interface that defines a fluid communication barrier within the valve. Parting the valve elements from one another removes the sealing interface to allow fluid communication across the valve elements. The valve includes a side port and a choke member that selectively blocks fluid flow through the valve when moved adjacent the side port and selectively opens the valve to fluid communication when moved away from the side port. The choke member remains adjacent the side port until the valve elements are spaced a distance apart greater than that at which valve erosion or fluid cavitation occurs.

Abstract: A cross reality system enables any of multiple devices to efficiently and accurately access previously stored maps and render virtual content specified in relation to those maps. The cross reality system may include a cloud-based localization service that responds to requests from devices to localize with respect to a stored map. The request may include one or more sets of feature descriptors extracted from an image of the physical world around the device. Those features may be posed relative to a coordinate frame used by the local device. The localization service may identify one or more stored maps with a matching set of features. Based on a transformation required to align the features from the device with the matching set of features, the localization service may compute and return to the device a transformation to relate its local coordinate frame to a coordinate frame of the stored map.

Abstract: A cross reality system that provides an immersive user experience by storing persistent spatial information about the physical world that one or multiple user devices can access to determine position within the physical world and that applications can access to specify the position of virtual objects within the physical world. Persistent spatial information enables users to have a shared virtual, as well as physical, experience when interacting with the cross reality system. Further, persistent spatial information may be used in maps of the physical world, enabling one or multiple devices to access and localize into previously stored maps, reducing the need to map a physical space before using the cross reality system in it. Persistent spatial information may be stored as persistent coordinate frames, which may include a transformation relative to a reference orientation and information derived from images in a location corresponding to the persistent coordinate frame.

The document is then processed to generate one or more tokens which are representative of the document. The document is then processed with a machine-learning model, such as a topic model, and a topic vector is output for the document. Based at least in a part on this topic vector, the document is then processed by one or more expert machine-learning models, which each output a probability vector. The various probability vectors are then further processed to calculate a total probability vector for the document. Based at least in part on the total probability vector for the document, a text output is selected.
